Swinging Sticks Kinetic Energy Sculpture

Product Information

For stroke survivors with gait deficits, slow walking speed is imposed by virtue of either or both balance impairment and limb joint discoordinated movements. Just as in healthy adults at slow gait speed, our results showed that stroke survivors walking at their chosen very slow speed had negligible KE in both thigh and shank. The result, as in healthy adults at slow speed, was the absence of conservation of mechanical energies ( KE/ PE) within the thigh and across the thigh and shank segments. In the absence of KE during the swing phase and in the absence of mechanisms of conservation of energy within the thigh and across the thigh and shank, stroke survivors were forced to employ some other means to advance the swing limb.

During imposed slow speed walking (<0.4 m/s), the advantage of KE was lost. The limb segments were moved with extremely low velocity throughout the swing phase, resulting in near-zero magnitudes of tKE and sKE, and also causing lower magnitude of overall TE oscillation. Therefore, during slow walking for healthy adults, key advantages of normal energy transfers were not available due to the absence of normal magnitude of tKE. First, there was no longer optimal transfer of mechanical energies within the thigh segment ( KE/ PE), which normally would have occurred during 0–56% of swing; that is, at chosen speed, there was decreasing tKE and increasing tPE during that subphase of gait. In contrast, during slow walking there was an abnormally low range of tPE magnitude between toe off and maximum hip flexion at the slow speed for healthy adults (Δ tPE subphase2). The concept was introduced by Franz Reuleaux, a mechanical engineer, in 1875. He proposed that rigid, overlapping segments were connected via joints and this created a system whereby movement at one joint produced or affected movement at another joint in the kinetic link.

Zahra Firoozkoohi Moghadam et al, concluded that both open and closed kinetic chain exercise had a positive effect on PFPS through decreasing pain and increasing the knee flexion range at stairs stepping, but the open kinetic chain had better results than closed kinetic chain exercise. [8]

InPutter was designed for research, analysis and training to improve the performance in golf putting. The engineered putter is equipped with an inertial measurement unit (IMU), force sensitive resistors and heartbeat radio-frequency receiver compatible with Polar electrocardiogram (ECG) transmitters. With a high frequency of 100Hz, the device can be combined easily with other alternatives, such as cameras, to increase the range of applications and variables for further analysis. The putter is able to maintain energy autonomy (battery capacity) for up to four hours, which is ideal for both ‘Pitch & Putt’ and traditional golf games. After describing the hardware and software development, this article highlights and assesses the benefits of InPutter by validating experimentally its function using the data collected from professional/expert golfers. However, in contrast to healthy adults, the stroke survivors were not able to employ muscle activations for normal balance control and normal joint movement coordination that were exhibited during the slow speed gait of healthy adults. Rather, the stroke survivors exhibited compensatory strategies for the swing phase according to residual muscle function available to advance the swing limb. In our stroke survivor sample, there were two compensatory swing phase patterns employed: Stepping Strategy or Circumduction. Vaughn C.L.

University Park Press; Translational kinetic energy — the most well-known type. It's related to the motion of an object traveling in a particular direction and the distance it covers in a given time. This is the kind of energy that you can estimate with this kinetic energy calculator.This confirms another systematic review performed on 12 studies that found “no differences between Open Chain and Closed Chain exercises in their effect on accelerated rehabilitation after ACL reconstruction”. They also found that a combination of Open Chain and Closed Chain exercises could be more effective to accelerate rehabilitation. [3] Neal R.J., Wilson B.D.
